To extend the life of your litter tray, do not put any litter underneath the waste trap lid when you pour the litter into the tray. Some people find that mixing the crystal litter once a week also extends the life of the tray. This is extremely beneficial if your cat is ill or has high urine output. It will also benefit cats that do not cover their waste or urinate consistently in the same spot. Be sure to mix the crystals from behind the rake and along the sides of the litter box. Do not mix the litter in the waste trap.

We recommend replacing the litter tray every 20 - 30 days for one cat, every 10 - 15 days for 2 cats, or every 7 - 10 days for 3 cats. You may need to replace the litter tray more often if you have: cats who eat a diet high in crude fiber, ash, and byproducts; cats over 10 years old; cats with health problems; and kittens under 6 months old.

The litter is saturated. As the crystals absorb urine, the litter will start to turn yellow. Once the majority of the litter turns yellow, the crystals are nearing their saturation point. When the crystals can no longer absorb any more moisture, you may start to notice an odour from the urine. This is an indication you should change the tray.

The waste trap is full. When the waste trap is full, the purple waste trap lid won't close completely. You may see small pieces of solid waste sticking out from underneath the lid. You may also start to notice an odour from the solid waste. This is an indication you should change the tray.

Some cats may require an adjustment period to get used to a new litter box. Here are a few tips to help with the transition.

Place the new litter box next to your cat’s existing litter box.

Allow your cat to have access to both the old and the new litter boxes for at least a week. This time may vary based on the temperament of your cat.

You may want to leave the system unplugged for a few days to allow your cat the opportunity to use the new litter box without any distractions. You will need to manually scoop waste from the new box until your cat is fully acclimated to using the new litter box.

Allow your cat’s old litter box to remain dirty. Cats prefer a clean litter box and this will make the new box more appealing.

Once your cat is acclimated to the new box, just plug in the system and your cat should find the new litter box clean and ready for use. Remove the old litter box from the area.

Animals learn by association, so you’ll need to adapt what your cat is peeing on now to the litter box in small, slow steps. If at any time your pet goes backwards a few steps, this is an indication you're pushing him/her too far too fast. Slow it down or even back up a stage or two, then try again, but at a slightly slower pace. Your pet only wants to make you happy, so continual praise and reward is the key!

If your cat is peeing on an object such as a small area rug or box:

Begin by having the rug near the litter box or Pet Loo. Make sure your pet knows where it is and uses it. Leave it like this for a few days.

Next, put the rug in the litter box or on top of the Pet Loo. Leave it like this for a few days.

Over the next week or two, reduce the amount of the rug showing in the litter box until you're either left with just litter in a litter box or the plush grass on a Pet Loo. For example, you can throw a handful of litter on the rug every day. Your cat will also probably throw some litter on the rug when she buries her waste, gradually covering it up entirely.

If your cat is peeing in a specific spot such as a corner or wall:

Move the litter box or Pet Loo on or near the spot. Leave it like this for a few days.

Once your pet is using the litter box or Pet Loo, you can start to move it to a better location. Over the next week or two, move the litter box or Pet Loo a few inches every day. For example, if your cat pees in the hallway and you want the litter box to stay in a closet, move the box an inch towards the closet every day. If your cat reverts back to the old spot, put the litter box back in the old spot and move the box in smaller increments less frequently.

The rake will not sweep if a cat is in the litter box because it will be obstructing the infrared sensors. The countdown timer will reset itself, so the rake will begin to sweep 20 minutes (or 5, 10, or 20 if you have ScoopFree Ultra) after your cat leaves the litter box again.

ScoopFree Original and Ultra are automatic; they automatically sweep waste after your cat uses the litter box. They have the same outer dimensions and useable litter bed space. ScoopFree Ultra functions like the original ScoopFree with three additional features for the ultimate in cat care:

The Premium Blue litter tray comes preloaded with Premium Blue Crystal Litter that stops odor 5 times better than clay and clumping litter. All Premium Blue litter trays come with a lid. When the tray is ready to be disposed, simply cover it and dispose of it.

The Scent Free Crystals Litter Tray is made from recycled materials (paper with no bleach added) and comes pre-filled with premium crystal litter free of perfumes and dyes. Free trays do not come with a lid so the trays nest, making them easier to stack and store in small spaces.

Rapid flashing indicates the sensors are blocked, which occurs when the cat is inside the litter box. If the indicator light is flashing rapidly and your cat isn't inside the litter box, it's possible that urine or other debris is blocking the sensors. To clean the sensors, dip a cotton swab in isopropyl rubbing alcohol and gently swipe inside the sensor holes on both sides of the litter box. After cleaning, unplug the litter box then plug it back in. The indicator light should return to a steady green.

Slow flashing indicates the litter box is in countdown mode, which occurs after your cat uses the litter box. The rake will sweep 20 minutes after your cat uses the litter box (or 5, 10, or 20 minutes after your cat uses the litter box if you have ScoopFree Ultra). The indicator light will return to a steady green once the rake is back in its home position.

Most cats adapt easily to the ScoopFree® box and use it within a week. If your cat needs help adjusting, try these tips:

• Leave your cat's old litter box next to the ScoopFree® litter box.
• Add a few handfuls of your cat’s old litter to the ScoopFree® litter tray and add a few handfuls of the ScoopFree® crystal litter in your cat's old litter box.
• Stop cleaning the old litter box. As the old litter becomes shallower and dirty, your cat should start using the cleaner ScoopFree® litter box.
• If your cat is startled by the raking noise, turn off the ScoopFree® box and scoop waste manually for a few days until your cat is used to the new litter box.

If you have a kitten under 6 months old, we recommend leaving the litter box unplugged and scooping waste manually. You can start getting her used to using the litter box with these tips.

• Kittens have a natural reflex to use the bathroom after eating, playing, or napping. Put your kitten in the litter box after these activities to help her associate the litter tray with the instinct.
• Place the litter box away from the food and water bowl. Cats prefer not to use the bathroom near where they eat and drink.
• Put the litter box in a quiet, visible place where she can get to it quickly. Getting all the way across the house to find the litter box could result in accidents. The location should also be safe and quiet so your kitten won't be startled or distracted.
• Keep the litter box clean. Scoop waste often and change the litter tray every few weeks. Cats and kittens prefer a clean litter box.
• Stir the litter crystals once a week to distribute saturated crystals. Kittens urinate more often than adult cats, so the litter box will get dirty more quickly.
